Remember suicides? No not the running drills you had to do in basketball practice. The other ones. If you’re not sure you know what they are, the image above illustrates them well. I had forgotten how much I like them, they’re also referred to as a half burpee, but still deliver results. The faster you do them, the more effective they are.
I warmed up with a short 2mi run and by the end of the whole workout, which only lasted 40 minutes, my core was really feeling the burn.
